Nice. Possible because of two things.
First: totality, uniqueness and relevancy. Stephen King had it right years ago when he wrote What Is A Brand?
Second: No company name. A company name appearing around the logo would change this a little bit. Like a small reminder that it came out of a meeting room or off of a desk. Nothing problematic with that, of course. It's just nice not to be reminded. Which points to the importance of visual hammers.
